Hi y'all - I'm trying to connect DVL double wall pipe to this thimble, but it doesn't look like an thimble I've seen in person, or online. The DVL pipe I have fits over the inner ring, but it isn't snug at all. I also have the 6DVL-ADT adapter. Again, same thing - everything "fits", but nothing is snug. Am I missing something? Another piece, or do I just need to screw something in? Appreciate the help - thank you!
